LUBRICANT. i

To all whom it may concern:

Be it known that we, ARMAN E. BECKER and LAWERENCE D. HisLor, citizens of the United States, residing, respectively, at Newark, in the county of Essex, State of New Jersey, and Elizabeth, in the county of Union, State of New Jersey, have invented new and useful Improvements in Lubricants, of which the following is a specification.

This invention relates to lubricants and will be fully understood from the following description.

In proceeding in accordance with our invention, we employ naphthenates primarily, modified as necessary with modifying agents. Depending upon the particular use in view, various naphthenates maybe used, for example'sodium naphthenate, calcium naphthenate, aluminum naphthenate, etc. Although the naphthenate may be purified if desired, we may also use the crude naphthenates, the crude sodium naphthenates for instance as obtained from suitable residuums having a wide range of desirable pro erties, besides containing also apro ortiono heavy oil base. For an average In ricant requirement, crude sodium naphthenate is com-- pounded with hydrocarbons of an amorphous character, such as petrolatum or still wax. As a rule, the still wax tends to result in products of greater consistency than those prepared by petrolatum. We may use petro latum as modifier for the sodium naphthena-te, or we may use still wax, or both, and in making up such compounds quite a wide range of proportions is available depending upon the particular use in view and the consistency desired. As examples, about parts of sodium naphthenate are mixed with about 40 parts of petrolatum; or again, crude sodium naphthenate about 50 parts is mixed with a petrolatum about 30 parts and still wax about 20.

If desired a small proportion of water up to 10%, but preferably about 1%, may be Application filed July 31, 1923. Serial 110. 654,925.

emulsified in the mixture. The effect of the water is to give initially a smoother working composition.

The precise grade of petrolatum employed may vary within comparatively wide limits, depending upon the precise character of the product desired. It is unnecessary that the petrolatum be especially decolorized.

While describing our invention, we have referred to certain specific details, it will be understood that this is by way of illustration in order to make the invention clear, and is not limitative, and in general, changes may be made which come within the spirit and scope of the invention.

We claim:

1. A lubricant comprising crude sodium naphthenate about 50%, petrolatum about 30%, still wax about 20% and water not to exceed 1%.

2. A lubricant comprising sodium naphthenate, petrolatum, still wax and water.

3. A lubricant comprising sodium naphthenate, petrolatum and still wax.

4. A lubricant comprising sodium naphthenate, petrolatum and water.

5. A lubricant comprising sodium naphthenate and petrolatum.

6. A lubricant comprising a naphthcnate and petrolatum.

7. A lubricant. comprising a naphthenate and an amorphous hydrocarbon.

8. A lubricant comprising sodium naphthenate, petrolatum, and still wax, said lubricant containing less than 10% water emulsified therein.

9. A lubricant comprising sodium naphthenate and petrolatum, said lubricant containing less than 10% water emulsified therein.

10. A lubricant comprising a predominating amount of sodium ,naphthenate com bined with a lesser amount of petrolatum.
